How does a Bluetooth headset work?

Bluetooth is a wireless short-range communications technology standard found in millions of products we use every day – including headsets, smartphones, laptops and portable speakers. A product with Bluetooth technology, such as a Bluetooth headset, has a tiny computer chip inside that contains the Bluetooth radio, and software that makes connectivity between devices possible.

So when Bluetooth-enabled products, such as a cell phone and headphones, are in close proximity to each other, they connect, or pair. This enables you to talk on the phone or listen to music without the bother of wires or cords.

Pair with a Phone

1. Make sure your Bluetooth headset is fully charged, turned on and compatible with the smartphone you want to pair.

2. Turn on the phone. Look for the Bluetooth feature, usually found under Settings.

3. Select On. (When you turn on the Bluetooth feature, the phone sends out a signal and starts scanning for other Bluetooth–enabled devices, such as your headset.)

4. When the phone finds the headset, the headset will show up on the list of devices. You will be asked to pair the devices by entering a PIN number. The PIN number should come with your headset. Usually the pin number is 0000).

5. Once the devices are paired, all your phone calls will connect automatically to your headset as long as it’s turned on, and you won’t have to repeat the pairing process.

Troubleshooting Tips

Turn everything off and repeat the pairing process.

Check the batteries in your headphone and make sure they are fully charged.

Check that your headset and phone are compatible.

A Bluetooth device emits low power radio transmission signals that can travel up to around 10 meters. But the distance can vary according to the headset. Check the range before you buy.
